Iago, an ensign serving under Othello, Moorish commander of the armed forces of Venice, is passed over in promotion when Othello chooses Cassio to be his chief of staff. In revenge, Iago and his follower, Roderigo, arouse from his sleep Brabantio, senator of Venice, to tell him that his daughter, Desdemona, has stolen away and married Othello. Brabantio, incensed that his daughter would marry a Moor, leads his servants to Othello’s quarters.
Meanwhile, the duke of Venice has learned that armed Turkish galleys are preparing to attack the island of Cyprus, and in this emergency he has summoned Othello to the senate chambers. Brabantio and Othello meet in the streets but postpone any violence in the national interest. Othello, upon arriving at the senate, is commanded by the duke to lead the Venetian forces to Cyprus. Then, Brabantio tells the duke that Othello has beguiled his daughter into marriage without her father’s consent.

Othello declares the night dedicated to celebrating the destruction of the enemy, but he cautions Cassio to keep a careful watch on Venetian troops in the city. Iago talks Cassio into drinking too much, so that when provoked by Roderigo, Cassio loses control of himself and fights with Roderigo. Cries of riot and mutiny spread through the streets. Othello, aroused by the commotion, demotes Cassio for permitting a fight to start. Cassio, his reputation all but ruined, welcomes Iago’s promise to secure Desdemona’s goodwill and through her have Othello restore Cassio’s rank.
